Create a tutorial for mobile (on-screen)

[ghalestrilo]

Some users pointed that an on-screen tutorial / tour of the mobile editor would be very useful. This is a very important feature for beginners with no design attempts / proposals so far.

Steps

1. Studying how other apps handle this (if they do)
2. Figuring out and ranking most relevant features to introduce
3. Trying out tutorial designs
4. Running user tests, iterating when needed
5. Creating the component and integrating it into the app
